Well, I know that the weight of the pole is 78.4 N and the light's weight is 117.6N, and that the light makes a 53degree angle with the pole, and since the sum of torques has to be 0, I need to separate the weights into their x and y components... the problem with that was I got stuck when I...
How should I be going about this problem? Here is the question, diagram, and my work:
A 50-story building is being planned. It is to be 200m high with a base 40m by 70m. Its total mass will be about 1.8X10^7 kg and its weight therefore about 1.8X10^8 N. Suppose a 200km/h wind exerts a force of...
#2: A traffic light hangs from a structure as shown in Fig. 9-60. The uniform aluminum pole AB is 7.5 m long and has a mass of 8.0 kg. The mass of the traffic light is 12.0 kg. Determine the tension in the horizontal massless cable CD, and the vertical and horizontal components of the force...
